SERVICE NOTES:
1. Although the hub plate appears to be a very substantial and solid part, it can be damaged. CAUTION should be taken
to prevent gouges, nicks, and scratches to the hub plate.
Check hub alignment every 100 hours. (Refer to pages 56-58, photos #8-13 and accompanying text.) The hub must
be re-shimmed if measurements are not within the following limits:
A. Hub centered within .001 T.I.R.
B. Hub pressure 8 to 12 lbs. using spring scale
The entire shimming procedure is covered later in this section.
2. The teeter block (part no. E49-5100) has a grease fitting that should have 4 shots of Mystik JT-6 grease every 25
hours. The grease should come through the bearing and be visible on the outer race of the bearing. Wipe off the
excess grease to prevent it from being thrown onto the blades during operation.
3. Check hub alignment every 100 hours. If the alignment falls within the prescribed limits, it is not necessary to re-shim
the hub.
The delrin shims as supplied are ready to install on the main drive pin. During final assembly of the hub to the main
rotor shaft, if you find the allowable tolerance is impossible to achieve, you may lightly sand the delrin shim with 400
grit wet and dry sand paper to remove .0005 to .001 inch of material. This final adjustment will allow you to shim the
hub within the .001 T.I.R. (total indicated reading) on final assembly. (Refer to the rotor hub shimming procedure later
in this section.)
